Hello,
If I try a simple 'mplayer -dvd 1'. mplayer segfaults. Here's my
attempt to give as much information as requested, following the
documentation (bugreports.html):

End of assembler dump.
My Distro: Debian GNU/Linux unstable
Kernel version: 2.4.18-rc4 i686
glibc version: 2.2.5
gcc version: 3.0.4
ld: version 2.11.93.0.2 20020207 Debian/GNU Linux
as: GNU assembler 2.11.93.0.2 20020207 Debian/GNU Linux
Attached is mplayer.log, containing the output of 'mplayer -v -dvd 1'.
Funny sidenote: mplayer -dvd 2 works fine. The DVD I'm trying to play
is American Pie, Region 4.
If there's need for more info, I'll be glad to help.
Thanks,
Carlos.
